"The audio files listed on this page illustrate various situations that are often heard in DX pileups. They are excerpts from real pileups recorded directly off the air in MP3 format. The files are recorded in STEREO with the DX station on one channel, and the pileup on the other. For best results listen in stereo with stereo headphones or ear buds. While you listen, imagine tuning the pileup looking for the station the DX operator is working. Studying these recordings could help you to gain an advantage."
